Leighton Meester wants mother’s lawsuit thrown out

“Gossip Girl” star Leighton Meester has asked a judge to dismiss her mom’s breach of contract lawsuit, insisting it’s based on a “non-existent” agreement between the pair.

Constance Meester is suing her famous daughter over claims the actress reneged on an oral agreement to pay her $10,000 every month for life.

But Leighton’s attorneys argue no such deal is in place. In a petition filed last week, the star’s legal team contends the suit should be thrown out since Constance is suing over “a non-existent management agreement.”

Leighton sued her mom in July in a bid to have a judge declare there was never any binding contract between them.

The 25-year-old also accused Constance of taking monthly payments intended for her sick brother Alexander and using the money to pay for cosmetic treatments.

Her mom launched a countersuit days later.

A hearing on the matter is scheduled for October 5, according to Eonline.com.
